Modes and manifestations of the explosive activity in the Earth's magnetotail, as well as its
onset mechanisms and key pre-onset conditions are reviewed. Two mechanisms for the …

More than half a century after the discovery of Pi2 pulsations, Pi2 research is still vigorous
and evolving. Especially in the last decade, new results have provided supporting evidence …

Dynamics of the near‐Earth magnetotail associated with substorms during a period of
extended southward interplanetary magnetic field is studied using a three‐dimensional (3 …

In magnetospheric missions, burst-mode data sampling should be triggered in the presence
of processes of scientific or operational interest. We present an unsupervised classification …

Recent global simulations of substorms show that before the onset of near‐Earth
reconnection the pressure equilibrium in the tail breaks down. This instability has no cross …

We use a novel coupled model of the magnetosphere-ionosphere-thermosphere system
consisting of the OpenGGCM magnetosphere model, the CTIM ionosphere-thermosphere …

We examine a near‐Earth current disruption/dipolarization (CDD) event in which two
THEMIS satellites were located at nearly identical equatorial projections but separated by …

Accurate evaluation of the physical processes during the substorm growth phase, including
formation of field‐aligned currents (FACs), isotropization by current sheet scattering …

Distinguishing the processes that occur during the first 2 min of a substorm depends critically
on the correct timing of different signals between the plasma sheet and the ionosphere. To …

Current sheet configurations in natural and laboratory plasmas are often accompanied by a
finite normal magnetic component that is known to stabilize the two-dimensional resistive …
